Read the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde. Evil besides (which I must still believe to be the lethal side of man) had left on that body an imprint of deformity and decay. And yet when I looked upon that ugly idol in the glass, I was conscious of no repugnance, rather of a leap of welcome. This, too, was myself. It seemed natural and human. What does the excerpt suggest about Dr. Jekyll?
